The numbers in parentheses indicate the average losses for (knights,
peasants). As N rises, the winning percentage goes up and the average
losses go down. The balance of losses seems to stay about the same as
well (knight losses are always slightly lower than peasant losses, as
in the regular system, since the dragon is 8% more likely to kill a
peasant in a single blow). This is all expected, since the dragon
picks targets randomly from the whole force.
